K&R says "Fields may be declared only as ints". The C99 rational says
"Three types of bit fields are now defined: plain int calls for
implementation-defined signedness (as in K&R), signed int calls for
assuredly signed fields, and unsigned int calls for unsigned fields".
I am surprised that the compiler accepted unsigned long, it is not
listed as a gcc extension. Do you get the same error when those fields
are changed to unsigned int?
